“Securitas’ themes are protection, ghosts and grounding. Her symbols are amulets and protective sigils. As the name implies, Securitas is a protective Goddess who watches over not only individuals in need but also entire empires. In the true sprit of security, She also actively promotes stability and firm foundations in our lives.
In ancient Rome, Lemures were considered to be the ghosts of family members who like to pester the living, if given the chance. So, in all due prudence, the Romans took time once a year to put ghosts back where they belong and invoke Securitas’ protection by tossing beans behind them nine times.
We can use this symbolism today in banishing any ghosts that linger in our figurative closets. Just name a handful of beans after your ‘ghosts’, toss them behind you in an open area, and walk away. This appeases the spirits and leaves the troubles behind you in the past, where they belong.
Today is an excellent day to make Securitas amulets for protection against mischievous spirits. Take any one or all of the following and bind them in a white cloth with red wool: sandalwood, sage, violet or peach pit. As you tie the wool, say:
‘Securitas’ power lies inside Where this amulet sits no ghosts may abide.’
Put the token wherever you need it. Eating leek soup keeps away spirits, too.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
Securitas was one of the many many “minor” gods and goddesses that the ancient Romans worshipped. She personified the security and stability of the Roman people, the Roman empire and the Roman emperor. “She was portrayed on coins from the Roman empire, typically with the attributes of a rod, sceptre, cornucopia and palm branch, standing or seated with crossed legs, as in the only known third century CE mosaic, surrounded by the inscription “SECURITAS IMPERIUM” on account of the fact that the Romans were convinced that the Goddess would guarantee the safe continued existence of the empire.
As we know today, she succeeded over a long period of time, bringing the allmighty Roman empire expansion on a previously unseen scale. With the decline of Roman mythology at the time of the fall of the Roman empire in 476 CE, the name slipped into obscurity only reappearing in Switzerland at the beginning of the previous century, when the history of Securitas continued successfully roaming across the continents. 
The only other reference I could find to Securita was that the Goddess Concordia (Goddess of agreement, understanding, and marital harmony) “was associated with a pair of female deities, such as Pax and Salus–or Securitas and Fortuna. The latter pair of concepts (security and fortune) could also be represented by Hercules and Mercury.” 
* A note on Roman deities – “A vast number of ancient Roman deities are known by name. The most familiar today are those the Romans identified with Greek counterparts, integrating Greek myths, iconography, and sometimes religious practices into Roman culture, including Latin literature, Roman art, and religious life as it was experienced throughout the Empire. Many of the Romans’ own gods remain obscure, known only by name and function, through inscriptions and texts that are often fragmentary—particularly those who belong to the archaic religion of the Romans dating back to the era of kings, the so-called “religion of Numa,” perpetuated or revived over the centuries. Some archaic deities have Italic or Etruscan counterparts, as identified both by ancient sources and by modern scholars. Throughout the Empire, the deities of peoples in the provinces were given new theological interpretations in light of functions or attributes they shared with Roman deities.”
